Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier
Answer:
heat
rainfall
Explanation:
heat and rainfall determine which traits are adaptive
Pretty sure it’s the endocrine glands they also produce and distribute hormones into the blood stream.
There are three types of galactosemia depending on enzyme deficiency.
<span>1. <span>Classic galactosemia which is an inborn autosomal recessive metabolic disorder which is caused by a deficiency of the enzyme galactose-1-phosphate uridylyltransferase. Classic galactosemia will result in accumulation of galactose-1-phosphate, galactose, and its derivatives, galactitol and galactonate.</span></span>
<span>2. Galactokinase deficiency is also an autosomal recessive metabolic disorder which results in accumulation of galactose and galactitol because </span><span>conversion of galactose to </span>galactose-1-phosphate <span> by </span><span>galactokinase is decreased</span>.
<span>3. <span>Galactose epimerase deficiency is an autosomal recessive disorder which is a result of a deficiency of the enzyme galactose epimerase. This disorder leads to the accumulation of galactose and galactose-1-phosphate.</span></span>
Answer:
1.helicase begins to break the hydrogen bonds between nitrogen bases.
free floating nucleotides pair up with exposed nitrogen bases.
dna polymerase attach the free-floating nucleotides to the exposed nitrogen bases.
two new molecules of dna are created.
cell starts into the mitosis phase of a cell cycle.
2. The hydrogen bonds holding the base pairs together in a DNA molecule are relatively weak compared to other chemical bonds. ... The new nucleotides join together to form the sugar-phosphate backbone of a new strand of DNA. The result is two DNA molecules identical to the original.
3.Each original DNA strand attracts new nucleotides that plug into their complementary bases on the original strand. The new nucleotides join together to form the sugar-phosphate backbone of a new strand of DNA. The result is two DNA molecules identical to the original.
4.Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. DNA replication always occurs in the nucleus.
